The paper discusses the improvement in bearing capacity of square footing placed at cohesionless soil reinforced with Geocell. Mohr - Coulomb failure criterion was used in the observations. To study effects of geocells with respect to planar geogrid, tests were conducted on planar reinforcement also. Numerical analysis results obtained by PLAXIS have been compared with those obtained from experiments and were found to be in good agreement. A parametric study revealed the role of length of reinforcement, spacing between layers, placement of reinforcement from top surface etc. on bearing capacity. A design example has been given to illustrate the savings in cost of construction of footing on reinforced sand. The study shows that improvement in bearing capacity with respect to unreinforced soil is of the order of 86% and settlement reduction is 13.07% for single layer of geocells which for double layers of geocells is 693% and 86.48% respectively. The cost reduction is 23.5% with respect to unreinforced soil.

In this paper, the large scale utilisation of lime mud in construction industry particularly in concrete works has been explored. Experimental investigations were carried out to evaluate the strength properties of Lime mud blended cement concrete. The nominal mixes of concrete M-15 and M-20 grade were considered and produced by replacing cement partially with lime mud. Cement in concrete was replaced with 0%, 10%, 20% and 30% with lime mud and a set of cubes were cast. The compression tests were carried out to evaluate the strength properties. Ultrasonic Pulse Velocity tests were carried out at 7 days and 28 days. Test results indicated that ordinary concrete can be produced by replacing cement with lime mud.

First oral bivalent live vaccine for immunization of pigs against F4 and F18 Escherichia coli post-weaning diarrhea MONTREAL, QUEBEC--(Marketwired - Nov. 15, 2016) - Prevtec Microbia Inc. is pleased to announce that its German subsidiary, Prevtec Microbia GmbH, received a positive opinion from the Committee for Medicinal Products for Veterinary Use (CVMP) of the European Medicines Agency (EMA), recommending the granting of a marketing authorization for Coliprotec® F4/F18 in the European Union. Coliprotec® F4/F18 will be the first single dose oral vaccine intended for active immunization of pigs against enterotoxigenic F4- and F18-positive E. coli, a causative agent of post-weaning diarrhea (PWD), a major cause of economic loss for swine producers. Through preventative immunization, Coliprotec® F4/F18 contributes to the health of piglets by reducing the incidence of moderate to severe post-weaning diarrhea (PWD) and the fecal shedding of enterotoxigenic F4- and F18-positive Escherichia coli from infected pigs. "The adoption of the positive opinion by the CVMP represents an important milestone towards the registration of Coliprotec® F4/F18 in the European Union," says Michel Fortin, President and CEO of Prevtec Microbia Inc. "We believe our product will be very well received by veterinarians and swine producers in the European Union and will contribute to the responsible use of antibiotics for Escherichia coli control, enabling a shift towards more sustainable farming", added Dr. Éric Nadeau, Vice-President Scientific Affairs. Following the adoption of the market authorization by the European Commission, Coliprotec® F4/F18 will be distributed in the European Union giving access for European Veterinarians and Swine Producers to an innovative product to better prevent both F4 and F18 E. coli causing post-weaning diarrhea. A temporary use authorization for Coliprotec® F4/F18 was recently released by the French Agency for Veterinary Medicinal Products (ANMV). Coliprotec® F4/F18 has been developed by Prevtec Microbia. Prevtec Microbia is a Canadian biotechnology company developing biological products for the prevention of diseases in food animals and as an alternative to antibiotics. The Company's mission is to find better ways to feed the planet by developing technologies that improve animal health and increase animal production performance.

Self Compacting Concrete - a highly fluid concrete mixture with no segregation and can compact under its self weight. The use of SCC is spreading all over the world, but it is in infant stage in India. SCC requires considerably more fines content as compared to traditional concrete to achieve self compactability. Looking at the potential of cementitious constituents in fly ash and availability in abundance in million tonnes as a byproduct of the thermal power plant demanding environmental solution, large volumes of fly ash, partially in substitution for cement and partially as filler, can be employed in SCC. The concrete grade for the study was chosen as M25 and mix for the normal concrete of this was designed by IS code method. In self compacting concrete, equivalent mix was chosen as per literature in reference. Self Compacting Concrete mix with selected superplacticizers and VMA with 40% fly ash content in total powder content were prepared and their properties in the fresh state viz, passing ability, filling ability and segregation resistance were studied for the assessment of the self compactability. Axial load carrying capacity of reinforced concrete column specimens and reinforced SCC column specimens were studied © EuroJournals Publishing, Inc. 2011.

In this paper, we propose a highly nonlinear dispersion flattened hexagonal photonic crystal fiber (HNDF-HPCF) with nonlinear coefficients as large as 57.5W -1 km -1 at 1.31 μm wavelength for dental optical coherence tomography (OCT) applications. This HNDF-HPCF offers not only large nonlinear coefficient but also very flat dispersion slope and very low confinement losses. Using these characteristics of our proposed PCF, it is shown through simulations by using finite difference method with an anisotropic perfectly matched boundary layer that this PCF offers the efficient supercontinuum (SC) generation for dental OCT applications at 1.31 μm wavelength using a picosecond pulse easily produced by commercially available less expensive laser sources. Coherent length of light source using SC is found 10 μm and the spatial resolutions in the depth direction for dental applications of OCT are found about 6.1 μm for enamel and 6.5 μm for dentin. © 2012 The Optical Society of Japan.

Philadelphia Water Department's (PWD)source water assessments (SWA) led to a carefully developed, multi-faceted plan that extends into two important watersheds, the Schuylkill River and Delaware River watersheds, and ensures protection of the region's water supply. By accomplishing watershed goals and building program capabilities, PWD has developed a source water protection program (SWPP). The SWPP employs science and research, innovation, ordinances, technology, and most important partnerships as mechanisms to accomplish program goals. The SWPP uses watershed partnerships, science, and research to implement upstream pathogen-reduction best practices. Through policy development and implementation in Philadelphia, PWD is poised to demonstrate to upstream partners stormwater management practices that protect source water quality. Source water protection also mobilizes organizations not regulated by national water policy and unites them with the regulated community around the common cause of maintaining one shared water. The SWPP uses a triple-bottom-line approach to pathogen reduction. Partnerships play an important role in all source water protection initiatives.
